Two teenagers were arrested by East Palo Alto police on Sunday on suspicion of shooting dead a 3-month-old baby. The incident left the baby’s parents seriously wounded. Investigators said it happened mostly because of mistaken identity.

The baby’s name is lzak Jesus Garcia-Lopez. His family including his parents and his 4-year-old brother were attacked in their car at 1 a.m. Sunday morning. They were just leaving a baby shower and parked on the 400 block of Wisteria Drive in East Palo Alto. Suddenly two gunmen appeared and shot the front and back seats of the car with small-caliber gunfire.

The police said the elder suspect was beaten by Sureno gang members in Redwood City on May 31 and he thought he saw one of the gang members get into a car in the same neighborhood - the 400 block of Wisteria Drive. He was supposedly taking revenge at the time.

The father of the baby, Oscar Jimenez, who sat in the driver’s seat, was shot in the shoulder and is still in hospital under treatment. Izak’s mother, who was in the back seat, got shot on her leg, while trying to save her two sons – 4-year-old Isaiah and 3-month-old Izak. Isaiah was not hurt in the shooting. However, lzak was shot in the head. He was pronounced dead a couple of hours later at 2:15 a.m.

During Monday’s news conference, lzak’s mother, Garcia-Lopez said with tears: He was such a precious angel; He is my everything. I was making my own little family and we were happy, and this person came into my life and destroyed it. They killed my baby and they killed part of my soul, too.

Police Chief Ronald Davis has called the killing a “tragedy” and has called for a stop on gun violence.

The police have withheld the suspects’ name because they are juvenile. The authorities found three weapons at the home of the suspects, including a gun believed to have been the one used in the Sunday attack, according to acting police Capt. Jeff Liu.
